// This is important because `git worktree list` will show a worktree being in a detached head state (which is true)
// when it's in the middle of a rebase, but it won't tell you about the branch it's on.
// Even so, if you attempt to check out that branch from another worktree git won't let you, so we need to
// keep track of the association ourselves.

// We need different logic for associated the branch depending on whether it's a main worktree or
// linked worktree, so this test handles both.
